れる。2. Description of the Prior Art According to the prior art, which is known in practice, cylinder heads are almost always produced by bulk casting. Usually, a mold is used, the boundary of which is formed by a permanent mold made of steel, for example. A sand core made of foundry sand is suspended in a molded permanent mold to produce a cooling water inlet passage, an outlet passage and a space in the cylinder head, a so-called water space.
【０００３】鋳造過程が行われた後まず砂中子が機械的

リンダヘツドの下部範囲に設けられる燃焼室を冷却水に
より最適に冷却することはできない。Due to the various parameters required by the casting technology, such as, for example, separation surfaces, draft angles or casting wall thickness, it is not possible to create an empty water space. As a result, the combustion chamber provided in the lower region of the cylinder head cannot be optimally cooled by the cooling water.

く形成せねばならない。[0005] The fact that the cooling water already has a strong impact towards the upper area of the water space by supplying it from the crankcase provided under the cylinder head is also a factor in the poor cooling of the combustion chamber. Contribute. Furthermore, it is necessary to always avoid casting accumulation in the casting parts, so that the water space in the cylinder head must be made much larger than is usually required.

No. 4,690,104 describes a cylinder head manufactured by casting for an internal combustion engine, which cylinder head has an opening in the upper region into which a pot-like part is placed. It can be screwed on. This component allows the cooling water stream to be directed towards the combustion chamber, and this opening is simultaneously used to remove foundry sand.

が生じる。However, the disadvantage of the relatively complicated screwing of the pot-shaped part is that it requires a further additional sealing device for reliably sealing the water space of the cylinder head. In addition, this cylinder head has significant mechanical costs for producing very large threaded holes for pot-shaped parts.

The majority of the cooling water flowing through the cylinder head is near the combustion chamber.

As a result of this improved cooling, the required output of the water pump is advantageously reduced, fuel consumption is reduced and knock tolerance is increased.

The cross section of the mold 1 shown in FIG. 1 further shows a sand core 6 forming an inlet passage and an outlet passage after the casting process. The sand core 6 is inserted into a core accommodating portion 7 provided in the lower mold 3.

効果を持つている。An excluding body 10 is inserted into the sand core 8 before the casting process. Before removing the sand core 8, remove the body 1
This is done by covering 0 with sand, thereby forming a sand core 8 for the first time. The foundry sand of the sand core 8 has a suitable insulating effect, depending on the material used for the exclusion body 10, in order to prevent melting or evaporation of the exclusion body 10 during the casting process.

空所５へ流入する材料で行われる。The rejecting body 10 has a fixed area 11 provided in the immediate vicinity of the core accommodating portion 9. The arrangement of the fixed area 11 is also possible at any point on the cylinder head, in order to allow a connection with the remaining cylinder head parts. By means of the fixing area 11, the excluding body 10 is first fixed in a manufacturing mold (not shown) of the sand core 8. The fixed area 11 after casting serves for connection with the remaining cylinder head part. In the casting process, the fixed area 11 is melted by the flowing material flowing into the cavity 5 through a supply port (not shown). The fixed connection and thus also the fixing of the displacement body 10 is effected with the material flowing into the cavity 5 during the casting process.

外からの付加的な密封をやめることができる。By fixing the exclusion body 10 via a fixing area 11 in the form of a closing plate in the production mold for the sand core 8,
In the next casting process, the opening for the core housing 9 can be closed. The savings in the core receptacle closure therefore provide the additional cost advantage of each cylinder head. Since the water space is sealed by the fixed area 11,
Additional sealing from the outside can be eliminated.

る。The excluding body 10 can be manufactured very simply and inexpensively from a two-part or several-part mold, not shown, for example by compression molding or casting. The casting process with the sand core 8 can take place in a known manner, despite its new construction. In addition, the excluding body 10 stabilizes the sand core 8 which is very likely to be destroyed without it.
【００２２】砂中子８の機械的除去により生じる水空間
は、公知の水空間に比較して著しく減少した体積を持つ
ている。なぜならば排除体１０は、シリンダヘツドの完
成の際、依然として水空間内にあるからである。The water space created by mechanical removal of the sand core 8 has a significantly reduced volume compared to known water spaces. This is because the excluding body 10 is still in the water space when the cylinder head is completed.

に生じる。By means of the exclusion body 10, the cooling water is guided in the direction of the combustion chamber provided in the lower region of the cylinder head. Combustion chambers also occur after removal of the sand core 6, as well as the inlet and outlet passages.

構造素子も含むことができる。Depending on the type of material used for the exclusion body 10 (often an aluminum alloy is used), the rigidity and strength of the cylinder head can be significantly increased. That is, depending on the material used and the associated casting temperature, it is possible to appropriately generate a compression preload or a tension preload on the cylinder head. This is obtained by the cooling material in the cavity 5 which clamps around the displacement body 10. This makes it possible to offset the loads which occur when the cylinder head is operated later, by means of a suitably selected compression or tension preload. Excluded body 10
Structural elements such as struts or ribs may also be included to reinforce the cylinder head.

簡単に構成される排除体１０も考えられる。The excluding body 10 shown in FIGS. 1 and 2 has a shape adapted to the condition of the cooling water in the water space. However, in an embodiment not shown, the excluding body 10 is formed into a mass to further optimize the flow. A finned grid spoiler configuration and a very simple rejection body 10 are conceivable.

上述したように燃焼室の高温壁へ集中せしめられる。In an embodiment, not shown, the displacement body 10 can be made of a material having a smaller density than the cooling water, so that after filling the internal combustion engine with the cooling water, the displacement body 10 is raised by the buoyancy generated by the upper area of the water space. So that they can float freely. Since a spacing piece can be provided above the cavity 5 or above the exclusion body 10, the flow of cooling water is still possible in the upper region of the water space. However, the main part of the cooling water is concentrated on the hot wall of the combustion chamber as described above.
